It's probably a packaging error, if he used the distribution's
packages. In that case, he should report the bug to downstream.

If he installed from source, then it's most likely installed somewhere
outside the library path, and the LD_LIBRARY_PATH trick might work (if
it doesn't, make sure there are no leftovers, recompile, reinstall and
it should work fine).
